Consider the sequence of steps to solve the equation:
x - 3
= x + 3
3

step 1 ⇒ x - 3 = 3(x + 3)
step 2 ⇒ x - 3 = 3x + 9
step 3 ⇒ x = 3x + 12
step 4 ⇒ -2x = 12
step 5 ⇒ x = -6

identify the property of equality which yields step 5.
a) division property
b) addition property
c) subtraction property
d) multiplication property

The answer is A) Division Property

Step-by-step explanation:

In step 4 we have:

-2x = 12

So find x, we have to divide both sides of the equation by -2 which is the coefficient of the x:

Therefore, we used the division property to find out X.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

answer: -2+√x,-2-√x
